What can cause xmlrpclib.ResponseError: ResponseError ()?

Question

I am experimenting with XML-RPC.

I have the following script server (Python):

from SimpleXMLRPCServer import SimpleXMLRPCServer

server = SimpleXMLRPCServer(('localhost', 9000))

def return_input(someinput):
return someinput

server.register_function(return_input)

try:
     print 'ctrl-c to stop server'
     server.serve_forever()
except KeyboardInterrupt:
     print 'stopping'

and the following client script:

import xmlrpclib

server = xmlrpclib.ServerProxy('http://www.example.com/pathto/xmlrpcTester2.py')
print server.return_input('some input')

I tested this locally and it works great. All he does is spit out the input from the client script, which is the correct one.

However, when I try to do this on a remote server, I get the following error:

Traceback (most recent call last):
  File "client.py", line 4, in <module>
    print server.return_input('some input')
  File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1199, in __call__
    return self.__send(self.__name, args)
  File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1489, in __request
    verbose=self.__verbose
  File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1253, in request
return self._parse_response(h.getfile(), sock)
 File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1392, in _parse_response
return u.close()
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line 836, in close
raise ResponseError()
xmlrpclib.ResponseError: ResponseError()

Any ideas what might cause this?

UPDATE:

when verbose=True:

Something else seems to be working on this port on the remote machine. And send an unexpected response.
